yuxtapa is a multiplayer real-time CLI game. It looks like a roguelike, but feels like a multiplayer 1st-person shooter with a focus on team play. The idea is to take the "feel" of such team based multiplayer games as Enemy Territory into an NCurses-based game with roguelike controls. Like roguelikes, yuxtapa is lightweight but surprisingly rich under the crude surface. It features several classes from which to choose, each with a different special ability, randomly generated maps which can also be saved and reloaded, and multiple game modes or objectives.

Universaltext Interpreter is a tool to produce written output (e.g. a prose book to be published, a dictionary in both electronic and paper format, or a Web site). It automates logical interdependencies and lets authors concentrate on the content and its structure. To use, an author writes the source information in plain text files or in word processor documents. The content structure is provided with an embedded unobtrusive prefix notation or with self-defined formats. You can navigate and query the source text structure with a script and generate from a single source multiple documents in different formats that extract all or some part of the contents.

advent4 is a port of the original Colossal Cave text adventure to Unix. It should work without any change on HP-UX, Sun Solaris, *BSD, and GNU/Linux systems. The actual license of this program is unknown, although most people agree that it is likely to be considered to be under the public domain.

wiggle is A utility that applies conflicted patches intelligently. When 'patch' fails, wiggle often can succeed by ignoring changes to the original file that are not relevant to the patch. The result should always be reviewed, as wiggle cannot notice semantic changes that are important.

foldroid is a mail folder selection tool. For people who use mutt or a similar text mode mail reader, foldroid is a convenient tool to navigate through your mail folders. It shows how many messages are in each folder and how many of them are new. This, combined with a tool like procmail to sort mail messages of mailing lists into separate folders, makes selecting the right folder to read easy. Foldroid works best when you run it in a screen session, because it then starts every instance of mutt in its own screen.
